How can I convert PDF to DWG with actual scale on my PC?

For a free and truly local way to do this, it's a pretty solid path, though it's not exactly a "one-click" solution. The goal is to convert PDF to DWG using a tool that runs entirely on your machine.

Here's a quick rundown of the main players you'd find in the command-line world:

pdf- to- dxf: This is a free, open-source Node. js tool that runs completely offline, so your files stay private. You install it via npm, and then you can run commands like pdf- to- dxf input.pdf output.dxf right in your terminal. The best part for you is it has a --scale option to apply a uniform scale factor, which is exactly what you need for your "actual scale" requirement. Just keep in mind it outputs DXF, not DWG directly, but most CAD programs handle DXF just fine.

psto edit: This is another classic, free, open-source command-line tool that's been around for ages. It can translate PDFs into a bunch of vector formats, including DXF, if you are going to convet PDF to DWG. It's a bit more old- school and relies on Ghost script to do the heavy lifting, but it gets the job done for free and locally. You can install it on Windows via winget.
